To aZZ 'whom it mag/concern,.- 4 Be it known that I, NICHOLAS CORNELIUS, ofthe city OfSt. Louis, in the State of Missouri, .u `haveinvented a certain new and useful Improvement in Roller Flour-Mills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawinlg s,1for|ning part of this specication, and in. W 1c Fig. II is a top or plan .view of the saine with,

My invention relates tocertain improvel ments in that classot-roller'llour-niills having... a cylinder within which is located a'roller, a 2o feeder for discharging the material to be ground, and a conveyer for removing the ma.- l -terial from the( cylinder; and myinventor consistsinfeatures of novelty, hereinafter fully' 4 described, and pointed out in the claims.

The' 3o interior surface of the cylinder and the exterior surface of theroll-er'are suitably dressed, and tlie'rnaterial to be operated upon4 is discharged within the cylinder above. the roller. The roller is placed in'such oloseproxi Inity'tofv serlalnwzossl (No model.)

I am aware that concaire 'stationary shoes adjustable to the periphery 'of the rolls -for the reduction of grain or other material are old; but it has been found that this method was entirely too harsh as a reducing operaf` tion, there being a total absence of crushing action, which rendered them unfit for this purpose, as the excessive grinding action pulverizes the-hull of the grain.

I am also aware that it is old to locate a crushing and grinding roller Within a cylinder, and to locate within such cylinder a feeder and discharge, the nearest point of contact between the roller and cylinder being at the bottom, E such a `device being shown in thepatent to C.

S. -Wenger, issued October 5, 1880. I, therefore, d o not broadly claim a combination of the hollow cylinder, roller, and discharge when the roller, feeder, and discharge are located within the cylinder; but

What I do claim, and; desire to secure by Letters Patent, is

1. In arollcr flour-mill, the combination of the cylinder, roller within the cylinder, and brush-edged conveyer located within the cylinder and brushing both the roller and cylinder, substantially as set forth. f ll, the combinationof 2. In a roller flour-m1 the cylinder, roller located within the cylinder, feeder located within the cylinder above the roller, and a brush-edged spiral conveyer located Within the cylinder beneath the roller v and brushing both the roller and cylinder,

substantially as and for the purpose set forth. NICHOLAS CORNELIUS.
